I am attempting to add CUDA support to the LAMMPS installation in Yggdrasil. However, I have been having trouble getting CUDA implementations to successfully compile. After some investigation, I found that the `came` command `find_package(CUDA)` fails to locate the CUDA Toolkit. I have attempted to set the `CUDA_PATH` and `CUDA_HOME` environment variables. I have also tried setting `CMAKE_PREFIX_PATH`, `CMAKE_INSTALL_PREFIX`, `CUDA_TOOLKIT_ROOT_DIR`, and `CMAKE_CUDA_COMPILER`. None of these helped to locate the CUDA toolkit. Does anyone have an idea what I need to set to make the CUDA toolkit discoverable?
